The Raiders terminated the contract of receiver/punt returner Roscoe Parrish, a day after he fumbled his first two opportunities at returning punts for the team. He was signed Tuesday after the Chargers cut him on Monday.

Oakland also waived 17 players, placed three on the reserve/injured list and, in an expected move, placed starting outside linebacker Aaron Curry on the Physically Unable to Perform list due to his bad knees. He is on ice for six weeks and can return to practice as early as Oct. 16.

Survivors – at least for a day as general manager Reggie McKenzie will assuredly bring in players off the waiver wire – are running back Mike Goodson, guard Lucas Nix, cornerbacks Chimdi Chekwa and Coye Francies, defensive tackle Jamie Cumbie and former San Jose State outside linebacker Carl Ihenacho.

(Francies fumbled a kickoff return in his debut Friday but Allen praised his special-teams coverage skills.)

Oakland kept seven cornerbacks and only five linebackers, underscoring the need for some more moves.

Curry was placed on the physically unable to perform list at the start of training camp because of the injuries. When he wasn’t healing as quickly as he hoped, Curry went to see a specialist in Los Angeles.

Allen said at training camp that he saw signs of improvement, but won’t activate Curry until he is healthy.

“When he demonstrates that he can bend and change directions full speed, then he’ll be ready to go,” Allen said.

Curry, the fourth overall pick by Seattle in 2009, was acquired by Oakland in for late-round picks in the middle of last season. He played in 11 games, starting nine, for the Raiders and had 32 solo tackles, three passes defensed and two fumble recoveries.

Stupar, along with Hamilton and Carrier, would seem like guys the Raiders would want to bring back and put on the practice squad today.

(Claims from other teams are due by 9 am Saturday, and then they can sign practice squad guys.)

“Stupar did some good things (Thursday),” said Allen, who had previously criticized the rookie for making the same mistakes over and over again. “He really did. I saw some instinctive football plays. He obviously was involved in several tackles, so it was good to see Nate make a few plays there in that game.”

“He came out last night and played and acted like he wanted to get a spot on this roster.”
